Description

Technical Field

[0001] This utility model belongs to the field of dust prevention equipment technology, and in particular relates to a dust prevention mechanism for a rod-type cylinder. Background Technology

[0002] A cylinder is a pneumatic actuator that converts the pressure energy of compressed air into mechanical energy. It mainly consists of a cylinder barrel, piston, piston rod, front end cover, rear end cover, and seals. Its working principle is that compressed air enters one end of the cylinder, pushing the piston to move. The piston then drives the piston rod in a linear reciprocating motion, thus realizing the transmission of force and the conversion of motion. Cylinders have advantages such as simple structure, reliable operation, low cost, and convenient maintenance. They can operate normally in harsh environments and are characterized by rapid action and sensitive response. They are widely used in automated production lines, machinery manufacturing, automobile manufacturing, food packaging, and other industries to achieve various actions such as clamping, pushing, and lifting. However, existing cylinders face challenges in harsh working conditions, such as: 1. Building materials and ceramics industry: Cement plants, ceramic tile production lines, glass manufacturing, etc., generate extremely high levels of dust; 2. Metal processing and casting industry: CNC machining centers (cast iron, aluminum chips), foundry workshops (dust, metal powder), welding workshops (fumes), painting lines (paint powder) (sandblasting process); 3. Food and pharmaceutical industries: Although the cleanliness requirements are extremely high, dust is also generated in the raw material processing (such as flour, sugar powder, milk powder), requiring dust-proof cylinders that meet food-grade (such as FDA) standards. 4. Timber processing and furniture industry: Wood chips and dust problems are very serious; 5. Packaging and handling industry: equipment such as palletizers and conveyor belts that operate in dusty environments; 6. Mining and metallurgical industries: The environment is extremely harsh, and the requirements for dust prevention and corrosion resistance of cylinders are the highest. At times, cylinder rod wear can easily lead to cylinder jamming and failure. Cylinder failure may trigger a series of chain reactions, which may result in production stoppages or even safety accidents.

[0003] Existing cylinder dust covers have limited sealing performance, allowing dust to easily intrude through the gaps in the cylinder body's grooves. They also have poor durability. During frequent extension, retraction, and torsion, stress concentration easily occurs at the root (fixed end) and head (follower end), leading to premature fatigue cracking. Installation and fixing require special tools, affecting maintenance efficiency. In addition, the dust covers are bulky and occupy the cylinder's extension and retraction stroke, resulting in poor versatility. Cylinders with dust covers on the market are generally custom-made models by manufacturers. Therefore, we provide a dust cover mechanism for rod-type cylinders to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a dustproof mechanism for a rod cylinder. By setting up the dustproof component, the problems of limited sealing performance, poor durability, inconvenient installation, and poor versatility of the cylinder dustproof sleeve in the prior art are solved.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a dustproof mechanism for a rod-type cylinder, comprising a cylinder body, wherein a dustproof component is provided on one side of the cylinder body; the dustproof component includes a dust cover sleeved on the surface of the output end of the cylinder body, a left contour cover provided on one side of the cylinder body, a right contour cover provided on one side of the left contour cover, a baffle installed on the output end of the cylinder body, and a buckle sleeved on the surface of the baffle.

[0007] The present invention is further configured such that one end of the dust cover is fixedly connected to the groove on the surface of the left and right contour covers by a strap, and the other end of the dust cover is fixedly connected to the surface of the baffle buckle by a strap.

[0008] The present invention is further provided that a guide rod cover is provided at the bottom of the cylinder body for sealing the guide rod hole at the bottom of the cylinder body.

[0009] The present invention is further configured such that the left and right contour covers are modeled with respect to the cylinder body using 3D contour modeling, and then fixed to the cylinder body by contour interlocking through 3D printing technology, so as to fix the end of the dust cover.

[0010] The present invention is further configured such that the buckle and the baffle are engaged by a slot and a block to ensure a durable and reliable end fixation.

[0011] The present invention is further configured such that the dust cover is woven from high-density fabric and carbon fiber material to provide excellent dustproof isolation effect and mechanical properties, and does not cause wear on the piston rod.

[0012] The present invention is further configured such that the dust cover has a preset extension margin in the free state, which is greater than or equal to the maximum stroke length of the cylinder piston rod, so as to ensure that the dust cover can effectively cover the piston rod during its full stroke reciprocating motion.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model significantly improves the dustproof performance of the cylinder block under harsh working conditions through the coordinated design of a dust cover, left and right contour covers, and baffle buckles. The dust cover is made of high-density woven fabric, which can effectively block micron-sized particles in the sandblasting environment of 3C manufacturing and metal chips generated by CNC machining. The left and right contour covers are 3D contoured and then fixed to the cylinder block by contour interlocking through 3D printing technology, forming a rigid fixed end of the dust cover. This avoids stress cracking at the root due to frequent expansion and contraction and prevents dust from entering through the gaps. The guide rod cover seals the guide rod hole at the rear of the cylinder block, forming a complete sealing system with the dust cover. This ensures that the piston rod and guide rod are in a clean environment throughout the entire stroke, fundamentally solving the problem of cylinder block jamming and failure caused by incomplete sealing of existing dust covers.

[0015] 2. This utility model optimizes the structural design of the dustproof components, significantly reducing maintenance costs while improving durability. The free expansion and contraction allowance of the dust cover is achieved through a pleated structure, and its length is precisely matched with the maximum stroke of the piston rod, avoiding fatigue fracture caused by excessive stretching. The split design of the left and right contoured covers, combined with the tie-fastening method, allows the dust cover to be installed without special tools, and can be disassembled and assembled by hand, improving maintenance efficiency. The antistatic layer of the high-density woven fabric lining can prevent dust adsorption, and the oleophobic coating on the surface is suitable for oily environments, extending the life of the dust cover and significantly reducing the overall cost of use and maintenance.

[0016] 3. This utility model adopts 3D contour modeling, and then uses 3D printing technology to manufacture structural parts, which can be matched with all domestic and foreign cylinder models on the market.

[0017] 4. This utility model integrates a high-performance composite dust cover, which is woven with high-density fabric and carbon fiber material, combining excellent dustproof isolation effect and mechanical properties. The inner antistatic layer prevents dust adsorption, and the surface oleophobic coating adapts to oily environments. One end of the dust cover is fixed to the contour cover, and the other end is connected to the baffle through a buckle, forming a dynamic sealing structure that expands / contracts synchronously with the piston rod. The guide rod cover seals the guide rod hole at the rear of the cylinder body, forming a complete sealing system with the dust cover. The pleated structure of the dust cover allows for free expansion and contraction, avoiding fatigue fracture caused by excessive stretching. Disassembly and assembly can be completed by hand, significantly improving maintenance efficiency and greatly reducing maintenance costs.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0026] Please see Figures 1-4 This utility model relates to a dustproof mechanism for a rod-type cylinder, comprising a cylinder body 1, with a dustproof component 2 disposed on one side of the cylinder body 1; the dustproof component 2 includes a dust cover 201 fitted onto the output end surface of the cylinder body 1, a left contour cover 202 disposed on one side of the cylinder body 1, a right contour cover 203 disposed on one side of the left contour cover 202, a baffle 204 installed on the output end of the cylinder body 1, and a buckle 205 fitted onto the surface of the baffle 204. The dust cover 201, fitted onto the output end surface of the cylinder body 1, is made of flexible high-density woven fabric and remains wrapped during extension and retraction. The piston rod isolates contaminants such as dust and metal shavings from entering the cylinder body 1, preventing piston rod wear from causing jamming failure. The left contour cover 202 and the right contour cover 203 are symmetrically arranged on one side of the cylinder body 1. The split design reduces the installation difficulty and tightly fits the cylinder body 1 to form the fixed end of the dust cover 201, preventing the root of the dust cover 201 from cracking due to stress concentration. The baffle 204 is installed at the output end of the cylinder body 1 as a support structure for the follower end of the dust cover 201. Its smooth surface design reduces the frictional resistance when the dust cover 201 moves. Example 2

[0027] Please see Figures 1-4Based on Embodiment 1, one end of the dust cover 201 is fixedly connected to the grooves on the surfaces of the left contour cover 202 and the right contour cover 203 by a tie, and the other end of the dust cover 201 is fixedly connected to the surface of the buckle 205 on the baffle 204 by a tie. A guide rod cover 3 is provided at the bottom of the cylinder body 1 to seal the guide rod hole at the bottom of the cylinder body 1. The left contour cover 202 and the right contour cover 203 are 3D contoured and modeled with the cylinder body of the cylinder body 1, and then fixed to the cylinder body by contouring interlocking through 3D printing technology to fix the end of the dust cover 201. The buckle 205 and the baffle 204 of the cylinder body 1 cooperate through a slot and a block to ensure a durable and reliable end fixation. The dust cover 201 is woven from high-density fabric and carbon fiber to provide excellent dustproof isolation effect and mechanical properties, and does not cause wear on the piston rod. The dust cover 201 is free The system has a preset extension margin, which is greater than or equal to the maximum stroke length of the piston rod in cylinder block 1, to ensure that the dust cover 201 can effectively cover the piston rod during its full reciprocating motion. The buckle 205 is fitted onto the surface of the baffle 204 and quickly fixes the other end of the dust cover 201 by mechanical engagement, allowing for disassembly and assembly without special tools, thus improving maintenance efficiency. One end of the dust cover 201 is fixedly connected to the grooves on the surfaces of the left contour cover 202 and the right contour cover 203 by a tie. The tie is made of wear-resistant fiber and can be adjusted to accommodate the fixing requirements of dust covers 201 of different diameters by a tie with adjustable tightness. The other end is fixedly connected to the surface of the buckle 205 on the baffle 204 by a tie. The cooperation between the tie and the buckle 205 forms a dynamic follow-up structure to ensure that the dust cover 201 expands or contracts synchronously when the piston rod extends or retracts, avoiding the accumulation of wrinkles in the dust cover 201 that would affect the sealing performance.

[0028] The working principle of this utility model is as follows: When the cylinder body 1 is working, compressed air pushes the piston rod to extend outward. The dust cover 201, which is fixed to the baffle 204 and the buckle 205, unfolds synchronously. The dust cover 201, made of high-density woven fabric, always keeps the piston rod completely wrapped during the extension process. At this time, the pleated structure of the dust cover 201 gradually unfolds, and its preset extension and contraction margin ensures that no tensile stress is generated. When the piston rod retracts, the dust cover 201 shrinks synchronously into the gap between the cylinder body 1 and the baffle 204 under its own elasticity. The tie fixing points at the left contour cover 202 and the right contour cover 203 avoid stress concentration through uniform force. The guide rod cover 3 and the dust cover 201 form a dynamic sealing system. During the entire movement, the dust cover 201 achieves double isolation of dust through the mechanical protection of the split fixed end and the flexible adaptation of the follower end. At the same time, its antistatic and oleophobic properties ensure stable operation in various industrial environments.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
